Section 1, Public Law 690, August 8, 1946 Patent expires June 15, 1959 2 Claims.

1 Frames for show-windows consisting of two different metal profiled members are known, the

. pane being held by the two profiled members and the latter being connected to each other by means of springs in such a manner that they can only be separated by the use of considerable force. In the case of other known frames consisting of two or more profiled members, screws holding the individual parts together are used as means of connection. All known designs present the drawback that'intricate profiled members are used in their making so that the finished frames are expensive and heavy.

The present invention relates to a frame intended especially for show-windows, consisting of one supporting and one covering profiled member, and provided with invisible slot ventilation, this frame being distinguished from the known designs in that the covering profiled member is connected to the supporting profiled member by means of slides which can be fixed to the supporting profiled member by means of screws, the screws and slides cooperating in such a way that the latter have a clamping effect on the covering profiled member.

In the drawing a constructional embodiment of the frame according to the invention is shown as follows:

Fig. 1 a vertical section of a Window-frame,

Fig. 2 a top view of a slide,

Fig. 3 a screw used to clamp the frame, on an enlarged scale.

The supporting profiled member of the frame is designated by I, the covering profiled member by 2. The'supporting profiled member I is either drawn from a piece of material or made by bending a steel tube to the required shape. It has a number of ventilation slots 3. These ventilation slots are inside a part of the supporting profiled member lying parallel to the glass-pane 5 and underneath a part projecting beyond its edge, so that they cannot be seen from outside. They extend to the bottom of a channel 6 which serves to collect the condensation water formed on the inside of the glass-pane under certain external atmospheric conditions.

The covering profiled member 2 is arranged edge upwards and has no long, horizontal struts so that it can easily be bent if necessary in order to be used for making bent show-window frames. This covering profiled member may also have a cross-section different to that shown. The essential thing is that the covering profiled member is equipped with two longitudinal grooves I slide to the and 8 one above the other and facing each other to receive the slides.

In order to attach the covering profiled member to the supporting profiled member slides are provided, as seen in Figs. 1 and 2, which are fastened with screws as in Fig. 3 to the supporting profiled member. The slides are of T-shaped cross-section, the flange 22 of which engages in the longitudinal grooves I and 8, whereas the strut is divided into two parts by a slot extending right up to the flange 22, which slot has a circular, conical enlargement through which the screws II are screwed into appropriate screwholes in the supporting profiled member. The strut of the supporting profiled member I is provided with slots [6 permitting of introducing the screws I7. The slides are inserted with the flange 22 into the covering profiled member, whereupon the la-tter is brought into the position shown in Fig. 1 in which the circular enlargements I9 are each arranged above a thread bore in the supporting profiled member, so that the screws I! can now be screwed in, the conical part 20 of the latter being wedged into the enlargements I9, thus causing the bending of the flange '22 and the clamping of the latter in the covering profiled member.

Between the covering profiled member and the supporting profiled member the glass-pane 5 is inserted in the known manner and secured by means of putty or any other suitable material.

The horizontal portions of the covering frame member 2 and of the supporting frame member I are provided with ventilating openings 2| and 3, respectively. Through these slots 2| air can enter from outside through the lower part of the frame 2, pass behind the pane 5 through the openings 3 and escape through the upper part of the frame through the openings 3 and 2|, as indicated by broken-line arrows.

I claim:

1. A frame for show windows and the like, said frame comprising a profiled supporting member, a profiled covering member, a class pane between said members, said supporting member having ventilation slots formed therein and located below said glass pane, whereby said slots are substantially invisible from the outside, said covermg member having guide grooves formed therein, slides whichare T-shaped in cross-section and have flange portions located in said guide grooves and strut portions, each strut portion having a slot extending from end to end of the strut portion and having an enlargement, and connecting members carried by said supporting member and extending through enlargements of the slots, whereby said slides clamp said covering member.

2. A frame for show windows and the like, said frame comprising a profiled supporting member, a profiled covering member, a glass pane between said members, said supporting member having ventilation slots formed therein and located below said glass pane, whereby said slots are substantially invisible from the outside, said covering member having guide grooves therein,

slides which are T-shaped in cross-section and have flange portions located in said guide grooves and strut portions, each strut portion having a slot extending from end toend of the strutportion and having an enlargement, and screws car- 15v 2,034,554

ried by. said supporting member and having conical heads fitting into enlargements of the slots, whereby said slides clamp said covering member.
